Our attorneys achieved two victories at the United States Court of Appeals for the Federal Circuit on behalf of client Berk-Tek LLC, a Nexans SA affiliate company, in the high-speed telecommunications cable industry.
In November 2012, our attorneys filed two of the very first inter partes reviews (IPR) challenging the validity of two patents for network cables held by Belden Inc., both of which are being asserted against Nexans and Berk-Tek in a parallel District Court proceeding in Delaware.
On April 28, 2014, the Patent Office declared that each and every claim of the two patents, U.S. Pat. Nos. 7,977,575 and 7,663,061, were invalid. Belden appealed to the Court of Appeals for the Federal Circuit and oral argument was held on March 3, 2015.
On April 17, 2015 the Federal Circuit issued a unanimous opinion, wholly affirming the Patent Office’s decisions that each and every claim of the two patents was invalid. The opinion was only the second ever to be issued by the Federal Circuit after review of a final decision from an IPR.
